PACKAGING

ALUMINIUM FLUORIDE (ANHYDROUS)

ICSC: 1324

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance HYGROSCOPIC WHITE OR COLOURLESS CRYSTALS. Physical dangers No data. Chemical dangers Decomposes on heating and under the influence of moisture. This produces toxic and corrosive fumes including hydrogen fluoride (see ICSC 0283).	Formula: AlF₃ Molecular mass: 84.0 Sublimation point: 1272°C Density: 2.9 g/cm³ Solubility in water, g/100ml at 20°C: 0.5 Vapour pressure, Pa at 1238°C: 133

Chemical dangers
Decomposes on heating and under the influence of moisture. This produces toxic and corrosive fumes including hydrogen fluoride (see ICSC 0283).

Formula: AlF₃
Molecular mass: 84.0
Sublimation point: 1272°C
Density: 2.9 g/cm³
Solubility in water, g/100ml at 20°C: 0.5
Vapour pressure, Pa at 1238°C: 133

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of dust and by ingestion. Effects of short-term exposure The aerosol is irritating to the eyes, skin and respiratory tract.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. Effects of long-term or repeated exposure Repeated or prolonged inhalation may cause asthma. The substance may have effects on the bone and central nervous system. This may result in bone alterations (fluorosis) and nervous system impairment.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of dust and by ingestion.

Effects of short-term exposure
The aerosol is irritating to the eyes, skin and respiratory tract.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

Effects of long-term or repeated exposure
Repeated or prolonged inhalation may cause asthma. The substance may have effects on the bone and central nervous system. This may result in bone alterations (fluorosis) and nervous system impairment.

OCCUPATIONAL EXPOSURE LIMITS
TLV: (as F): 2.5 mg/m³, as TWA; A4 (not classifiable as a human carcinogen); BEI issued. EU-OEL: (as F): 2,5 mg/m³ as TWA. MAK: (as F, inhalable fraction): 1 mg/m³; peak limitation category: II(4); skin absorption (H); pregnancy risk group: C

ENVIRONMENT

NOTES
CAS 15098-87-0 and 32287-65-3 are for hydrated forms. Temperature of decomposition is unknown in the literature. The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact.
